Nobody recommends a water change when all parameters are exactly right. But that is basically impossible to test

The water change recommended after the bottled bacteria cycle is because you're going to have a large buildup of the converted ammonia you dosed. Otherwise you have to export it somehow

No bottled bacteria here. Fish less Cycle. With LR and LS and patience.

Can you share how exactly you do this? As to the OP - there is no reason to change water if your nitrate is ok.

So basically a 'fish in cycle' - with more frequent water changes. ?
